MACHINE FOR STAMPING SOLES OF BOOTS OR SHOES.

SPECIFICATION forming part of Letters Patent No. 402,803, dated May 7, 1889.

Application filed November 15, 1888. Serial No. 290,9? 6. (No model.)

To aZZ whom it may concern.-

Be it known that I, MICHELLE E. BYRON, of Pepperell, in the county of Middlesex and State of lWIassachusetts, have invented a new and useful Improvement in Machines for Stamping upon the Soles of Boots or Shoes, which invent-ion I will describe as follows, reference being had to the accompanying drawings, which form a part of this specification, like letters indicating like parts in the different figures thereof.

Figure 1 of the drawings is in perspective and shows my machine when out of gear. Fig. 2 is partly in elevation and partly in section, and shows the machine in gear and as it appears when in operation. Fig. 3 is to illustrate the oscillating of the block that holds the dies. Fig. 4 is an enlarged perspective of one of the die-blocks. Fig. 5 is a vertical longitudinal section showing the block for holding the dies, the two die-blocks, and the screw for moving said die-blocks apart or toward each other, which screw has a right thread for half its length and a left thread upon the other half. Fig. 6 is an end elevation showing the block which holds the dies and the method of supporting and holding said block. Fig. 7 is a bottom plan of the dies and blocks. Fig. Sis a plan of the cam, which is an important factor in turning off the standard which holds the boot after the sole thereof has been stamped, all of which is hereinafter fully described.

My invention consists in a device forstamping the soles of boots or shoes, the dies for such stamping being so constructed and ad- 3' usted that the marks, letters, or numbers produced by the dies severally shall be as near together or as far apart upon the sole of the boot as desired, and that the dies will adjust themselves to the sole of the boot exactly,

' whether said sole be made more or less conholds the boot from under the dies when the operation is completed; also, a method of adjusting the standard that holds the boot to provide for stamping soles of different thickness.

A is a pulley connected with the source of power by the belt B, said pulley serving as a loose pulley when the machine is out of gear and a tight pulley when it is in gear. This pulley is made fast to the shaft A, and the gear A is also fast upon said shaft, all of which is fully shown in Fig.1 of the drawings.

E is an eccentric gear upon the shaft E. The shifter O has its inner end made in the shape shown at the point 0, as shown in Figs. 1 and 2, for the purpose of holding the shaft E when the machine is out of gear. The spring C raises the outer end of the shifter O, and thus enables the end 0 of the shifter to hold the shaft E and keep the machine out of gear. It will be observed that the arm D moves upon the shaft d, as shown in Figs. 1 and 2, and said arm,'together with the eccentric gear E, is attached to the shaft E. Thus it will be readily seen that when the operator presses his foot upon the end 0 of the shifter O, and thus raises the opposite end thereof, the spring D draws the lower end of the arm D back, and with it the eccentric gearE, both being upon the same shaft, E, so that said eccentric gear meshes in the gear A and the machine is then in gear, as shown in Fig. 2.

When the operator removes his foot from the shifter C, said shifter is brought down upon the shaft A by the action of the spring C and is ready to again take hold of the shaft E when said shaft shall come round with the eccentric gear E.

G is a standard, upon the upper end of which is placed the boot the sole of which is to be stamped. After the boot is placed thereon the operator turns with his hand the standard G, so as to bring the boot under the dies 2' t', as shown in Fig. 2. The screw g, turned by means of the wheel 9 or by any other suitable device, is for the purpose of adj ustan important feature in this machine. It is made fast round the standard G, so that it moves with said standard. hen the stand ard under the dies 1' i ready for work, this cam G has the pin h for a bearing. The rod II is held to the frame I. of the machine by the pivot 71 and moves upon this pivot. Near the upper end of the rod II is the arm 7L, said arm being provided with a spring, 7r", as shown clearly in Figs. 1 and 8, to prevent breakage when it comes back and strikes the cam G. An examination of Fig. 2 shows the rod 'm connected with the rod II by and mov i ng upon the pivot 71?, the opposite end of said rod m being held to the arm D in and by means of the slot and set-screws shown at m. This rod on may thus be held to the arm I) at right angles therewith, or may be moved up or down to regulate the rapidity with which the arm I) will be drawn back after the operation of stamping has been accomplished.

The operation of the part of my machine the construction of which has just been described maybe explained as follows: The machine is placed in gear by the operator pressing his foot upon the shifter C at the point e, as has been hereinbefore fully described. Now that the machine is in gear and the co centric gear E meshes in the gear A and said eccentric gear is attached to the same shaft, E, to which the lower end of the arm D is held, it is obvious that the eccentric gear first moves the lower end of the arm D outward, and as said arm D is moving upon the pivot (Z the effect is to bring the dies i 1' down upon the sole of the boot which is upon the end of the standard G and with such power as to stamp said sole. After the dies have done their work upon the sole of the boot, the spring I) draws said arm D back, and this arm D, being connected with the rod II by means of the rod on, said rod II is forced back, the arm 7L strikes the cam G, and the standard G is turned around so that the boot may be removed therefrom and another be placed there on. The pieces designated a are merely to form a guide to the arm 1).

A very important part of my invention relates to the construction, arrangement, and operation of the dies for stamping, to which reference has been previously made.

For brevity in the description I designate the dies and the blocks to which they are attached together as '23 1', as a block and its die are practically one thing.

I the main block, and i is a slot in the arm ]'),in which there should be sufliciez'it room for the block I to oscillate. This is fully illustrated in Fig. The belt (Z is to hold the block I in place, and is pivoted to said block at the point I, as shown in Fig. (i, to admit of the oscillation above mentioned. The spring (1 .is for the purpose of cushion- 111g.

M is a screw inserted partly in the main block I and partly in the die-blocks '1' 1'. The

screw works, however, in the die-blocks, the slot in the main block I being only a smooth slot. At the end of the screw M there should be some suitable handle for turning, as M. The pin 41?, working in the slot '21 is for the purpose of holding the screw M when it is turned to the desired point.

An examination of the drawings, especially of Figs. 5 and 7, will show that the screw M has a right thread for half of its length and a left thread for the other half. By this arrangement it is obvious that by turning the screw M one way or the other the dies 1. 11 may be placed near together or far apart, and thus the letters, figures, or marks produced by each die may be made to appear as near to gether or far apart upon the sole of a boot as desired.

The two sprin n or (shown clearly in Fig. 5) are equaliZing-springs, each one bearing upon the block I in one direction and upon a plate between said spring and its adjustingbolt '71 in the other direction. The bolts '11. n are for regulating the tension of the equalizing-springs 'n 02 \Vhenthe dies 11 "11 are brought down upon the sole of a boot, the es cillating of the main block I, regulated by the two equalizingspings n 92. the tension of which is governed by the bolts '11. w. withtheir nuts or 17;, makes it certain that the dies 1'. 1 will be placed fully and completely upon the sole of a boot, and thus the fullness and completeness of the stamp upon said sole will be secured, Whether said sole be more or less convex in form.

l'laving fully described my lTlV0l1lJl()l'l,ll&lJ I claim as new, and desire to secure by Letters Patent, is

1. In a machine for stamping the soles of boots or shoes, the main block I, oscillating in the slot 1" and provided with the adjustable equalizing-springs n n, the die-blocks 11 i, moved by means of the screw M, which is provided with a right and left thread upon each half of the screw, respectively, in combination with the arm D, and the standard G, constructed and arranged substantially as described and shown, and for the purposes set forth.

2. In a machine for stamping the soles of boots or shoes, in combination, the arm I) and eccentric gear E, both attached to the shaft E, the shifter 0, provided with the spring 0, the gear A attached to the shaft A, the spring D, the rod II, equipped with the arm 71. and connected with the arm D by the adjustable rod 971, the cam G, made fast to the standard G, said standard being provided with. the adjustable screw 9 and with the cushioning-spring y, the wholeconstructed and arranged substantially as described and shown, and for the purposes set forth.
